- IMPROVEMENT IN LAMP-BURNERS.

Specification forming part of Letters Patent No. 188,347, dated March 13, 1877 application tiled December 9, 18.76.

To all lwhom it may concern.'A

Be it known that I, UHARLEs A. FERRoN, of Paris, France, have invented a new' and Improved Lamp-Burner, of which the following is a specification:

In the accompanying drawing, Figure l represents a vertical central section of my improved lamp-burner Fig. 2, a side elevation of the same with exterior parts detached to show inner guide-tube and spur-wheels. Figs. 3 and 4 are top and bottom views of the burner with exterior parts detached; and Figs. 5 and 6 show, respectively, side and top views of the Wick used in my burner.

Similar letters of reference indicate corresponding parts.

My invention is designed to provide a round burner for petroleum and other lamps, that produces a vsuperior light by the increased supply of air to the interior and exterior surfaces ofthe flame, and furnishes a wickthat may be adjusted in uniform manner, and arrested at a fixed point in being turned downward.

The invention consists of an interior fixed, and an exterior detachable, guide-tube for the. Wick, to which the air is supplied from the outside through the base ofthe dome, and the inside through a radial air-channel of the conical base, arranged around the stem of the Wick adjusting spur wheels. The wick is evenly adjusted by intermeshing double spurwheels in connection with flat side springs otl the base part. The upper part of the wick is closed, while the lower part is open, the closed part being arrested in its downward motion by a radial stop-plate or partition of the base section. The chimney, globe, and dome holder is supported on a collar of the base-section,

, and by a guide-ring on the outer wick-tube.

Iu-the drawing, A represents the interior wick-tube, that is secured rigidly to a conical base part, B, which screws, in the customary manner, on the collar of the lamp-bowl. C is the detachable exterior wick-tube, which is, like the inner wick-tube, ot' cylindrical shape, and concentric thereto. The lower part of the outer wick-tube screws into the threaded top collar of the base-section B, and is taken off when a new wick is to be inserted. The intethrough the airchannel A', and having a dou` ble spur-wheel at the inner end, which intermeshes with a second double spur-wheel, E',

whose shafts are supported in lateral plates a of a horizontal plate, b, of the base B, theloWer plate b having a perforation, b', for the admission of air to the bowl.

The double spurwheels E E' bear, at diametrically opposite points, on the inside of the wick, and n iove the same evenly 1n connection with band-springs d, that are soldered at the ends to the base-section B, bearing on the outside of the wick D. The upper part of' the wick is closed by sewing the edges together, or otherwise, as shown in Figs. 5 and while the lower part is flat, and passes down into the liquid at both sides of the air-passage A' and the spur-wheels E E'.

By removing the outer wick-tube the wick may be readily inserted and. taken hold of by the spur-Wheels, and lowered by the same until the closed section comes in contact with' a partition or stop-plate, e, extending from the inner to the outer. wick-tube centrally abovethe air-passage A', as shown in Figs. 2 and'3. rlhe partition-plate arrests the downward motion of the wick, and retains the same positively in the wick-tube without danger of turning the same down into the bowl, indi--v eating also the downward position of the wick and the direction in which the stem of the spur-wheels has to be turned for raising the wick.

This feature forms an essential point of my burner, as the advantage of so simple a mechanism for retaining the wick at a fixed point without the possibility of releasing the same from the action of the spur-wheels is readily perceptible.

A cylindrical holder, F, with broken-out parts, is seated on a collar, F1, of the basesection B. The holder F supports the chim' n'ey, globe, and cone F2, and is guided along the outer wick-tube by a ring, f, that slides along the Wick-tube when the holder F is taken oi' or replaced for cleaning, inserting 2L wick. and other purposes.

` The dome is seated in detachable manner on an interior annuler and ring-supporting coller or molding, f', of the holder, to he teken oli' for trimming the wick. The burner facili tates'the insertion of the wick, accelerates the supply of oil, feeds the Wick in regular menner, and furnishes arfull supply of air to the inner and outer surfaces of the Heine, so as to produce a bright andeconomiczil light, and an elegant and reliably-working burner.

Having thus described my in vention, I claim as new and desire to secure by Letters Patent t 1. In a lamp-burner, the combination of the conical base-section, a fixed interior Wick-tube, 'and an exterior detachable Wick-tube, for in- CHARLES AUGUSTE FERRON.
